Daily sharing of Golang-related technical articles, practical resources, language news, tutorials, real-world projects, and more. Looking forward to growing together. Let's go!
This guide compiles practical Nginx performance‑tuning directives, FastCGI settings, Linux kernel parameter adjustments, security hardening tips, and monitoring configurations, providing concrete examples and command‑line snippets to help sysadmins and developers optimize high‑concurrency web services.
The article explores why concurrent programming is notoriously difficult, arguing that the root cause lies not in human cognition but in the combinatorial explosion of possible states and interleavings, and presents heuristics for reducing state space, such as using processes, atomic operations, and language constructs.
This article walks through the concepts of forward and reverse proxies, explains HTTP and HTTPS proxy protocols, and provides a complete, step‑by‑step Golang implementation with code samples and diagrams for building a functional HTTP proxy server.
This guide explains the essential Go commands—including build, install, get, doc, godoc, test, list, and fix—detailing their purposes, typical usage scenarios, and how they help developers compile, manage dependencies, document, and test Go code efficiently.
This guide outlines a comprehensive Go project layout—including cmd, pkg, internal, test, configs, and docs directories—alongside modular design principles, middleware usage, dependency injection, error handling, logging, database access layers, testing strategies, performance tuning, and documentation practices to improve code readability, maintainability, and scalability.
The April TIOBE Index shows Python gaining market share while C and C++ lose ground due to memory‑safety concerns, PHP slipping to historic lows, and a broader shift in developer preferences driven by AI, web frameworks, and security considerations.
This article walks through creating a lightweight API gateway in Go using the standard net/http/httputil ReverseProxy, explains its core concepts, compares it with other gateway solutions, and provides a complete, runnable example that routes authentication and user services.
Go 1.22 dramatically improves runtime tracing by cutting CPU overhead to 1‑2%, adding scalable trace splitting, introducing an experimental blackbox recorder, and providing a new trace reader API, all illustrated with practical code examples for diagnosing goroutine blocking and network stalls.
This article walks through nine Go‑based implementations for the 1‑Billion‑Row Challenge, starting from a straightforward scanner approach and progressively applying map pointer values, custom parsing, integer arithmetic, buffer tweaks, custom hash tables, and parallelism to shrink processing time from 1 minute 45 seconds to under 4 seconds.
This article reveals lesser‑known Go language details, covering numeric literal formats, slice expression variations, test result caching with go test, and how to disable HTML escaping during JSON serialization, complete with code examples and output.
